Stand with a slight bend in your knees, holding a dumbbell in each hand. Bend forward from the waist about 45 degrees and extend your arms toward the floor, as shown.
Exhale and bring your arms out to the sides, leading with your pinkies and squeezing your shoulder blades together. Lift until your arms are parallel to the floor. At the same time, extend your right leg back, keeping your weight on your left leg. Inhale as you lower the dumbbells and return the leg to the starting position. Repeat with the other leg.
